Most quartz sand deposits explored in the country are located in south and southeastern Brazil (Ruiz et al., 2013, Cruz, 2011) and are widely used by float glass manufacturers. Those resources, however, are not as pure as the rocky quartz deposits, what make them unattractive for silica glass manufacturers.

1.1 Silica sand processing Nature separates and purifies silica sand to a great degree but further processing is needed to produce sand sufficiently pure for modern uses. Current processing technology can upgrade sand deposits that are not naturally pure enough for glass making. Consistency is of paramount importance for most silica sand users.
